    Default 430nm Quantum

    Hiya Talk

    I seriously reckon the 660nm Quantum strips are the dogs nuts. My yields are through the roof.

    So, I have bough 4 x 35W 430nm Quantum Strips. Lets up the Blue!

    I will run 2 strips in series with the 660nm. The other two for prop tent

    I cannot wait to see what the combined effects will have. 265W 3500K then 80W @ 660nm & 80W @ 430nm

    Mon the 420W mixed Quantum!

    New tech rocks!

    Nice, there seems a lot of differing opinions on what LED wavelengths to go for. Might have to order me some deep red and far red LEDs. Not sure how good my surface mount soldering is...

    My far red came as a bult strip with heat sink on top.

    The blues I have opted for are the same. Not sure if I can use the single driver to run all four strips.

    I have a spare driver if not.

    The plan is to cable tie the blue strips to the red



    Reckon there must be a market bringing these strips over from China. Perhaps even making combo strips.

    They are very popular in the reef tank community where they are mixing 4 strips on top of a main white.

    They then mix the spectrum over the day via computer to simulate daylight -> nightlight.

    The boards seem reasonably priced but I can't part with my money when I know they are paying <0.10 an LED. Totally worth the money if you have no interest in making PCBs.

    As long as the driver can output the total amps required and the boards run at the same voltage you should be able to wire them all up in parallel.

    I was thinking if it would make a difference if you slowly brought up lights in the morning and reverse in the evening would it make your plants happier? Never fun being woken up quickly.

    QBS are the future,I said it 18 months ago when all the doubters said bollocks.
    It's nice to be nice.

    Weve got deep an far red strips an boards

    Uk manufactured and lm301h chipset the very latest.

    We also have some veg strips with royal blue and 5000k coming out for clone an seedlings very soon.

    Again uk manufactured

    And then we are dropping our own version of a spyda type light very soon.

    Lots going down at the moment.

    So first combo QB11 strip built and ready to be installed tomorrow.

    I have ordered a load of graphic card heat sinks to mount on top.

    The blue is BRIGHT! May well fit the second set in the tent, but waiting on another driver.

    Tested the first unit and drawing 32W which seems very low. I may look for a better driver.



    Time to build the next unit.

    There's only 11 LED's, shouldn't be using 32W. If a unit is 4 of them then 32W makes sense.

    Yeah sorry that was all 4.

    Got my Mean Well driver today (decent dimmable on unit one with earth and waterproof) and at max is 42w so roughly 1W a diode?

    Are you wiring the red and blue together? Looks like they run on different voltages. What voltage are you running at?

    Yeah I am ... that explains why they were dull wired as a combo!

    I will run each pair off a separate driver!

    Thanks Agent Green - knew I had bug%%rd something!

    Can also use a single driver if you series connect them

    Today I managed to build the "arms".

    I am waiting on some heat conductive glue so that I can attach the 660nm in the middle of the 430 / 670 strips. Test fired and oh so bright! I had spots for ages! Doh!

    The ballasts have been mounted outside the tent in a vented box and wired through the tent and down from the roof.

    Bl***dy hard with 7 plants and p!ssing down!

    I am using 4 ballasts, one for each colour. I am not sure I needed to, but it works properly now! On the plus side, each is on a WIFI controlled plug. So nice and convenient from phone.

    Luckily I have a spare 288 IS panel, which the arms could be attached to. Even more convenient that the heat sinks are drilled..... Took me a while to figure out how to do this neatly!

    Tomorrow I just need to remove the old IS 288 panel and 660nm strips, stick on the 660nm to the new frame, rehang and wire up 4 x ballast. Should be pretty simple.

    Using aluminium, the total weight is negligible.

    Oh and attach heat sinks to the new strips. (adhesive sinks, one per LED).

    I have used Wagu connectors on each input as I found I could break the plastic housing too easily. This way 1 time fit . After that just a lever. I am oh so clumsy!



    Sh!t gets real tomorrow ppls!

    Doh think I blew three of the boards.

    Agent Green is correct. They run different voltages.

    The static held in the driver blew out the 670nm..... @rse. None will work wired singularly now.

    Ordered more! Bah!

    Can I use the same driver but use two of them - one for each pair? (Mean Well pcd-40-350B)

    Wish I knew sh!t about leccy! ton of hard earned down the pan.

    Its current that blows leds not voltage. Provided you limit the current, the driver will supply the correct voltage ( within the range the driver can supply)

    You can run all the colours of the rainbow at same time providing you dont allow too much current through them.

    Driver choice is key

    That's a shame, doesn't look like they added any current limiting resistors to the board either.

    Worth reading up on electricity. It's pretty simple as long as you can maths. If you struggle with equations then you are out of luck but all you really need is V=IR

    Frying electronics is all part of learning.
